Answer:
An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.

Explanation:
The final velocity of the skateboarder I after the collision is 3 m/s to the left.
<h3>
Velocity of skateboarder I</h3>
The velocity of skateboarder I is determined from the principle of conservation of linear momentum.
m1u1 + m2u2 = m1v1 + m2v2
50(0) + 75(0) = 50v1 + 75(2)
0 = 50v1 + 150
v1 = (-150)/50
v1 = - 3
v1 = 3 m/s to the left
Thus, the final velocity of the skateboarder I after the collision is 3 m/s to the left.
